Interesting timing on this article considering The Big Walk comes out this week. Obviously the game is not as intricate as a Myst game, but it feels like the perfect mixture of a game where design really matters and reaction to what the market wants. People like playing together and collaborating to make their own fun. It is not hard to imagine a version of Myst like this -- the most fun I have had playing a PC game was sitting next to a friend as we played Riven beginning to end.
